With the clone in hand, the two had a decision to make. Since Prasher cut the GFP gene out of the jellyfish genome with restriction digestion enzymes, the clone had extra DNA segments that bookended ...

The axolotl (Ambystoma mexicanum) has extraordinary regenerative abilities—the salamander can regrow lost limbs and repair ...

fluorescence and red is chlorophyll fluorescence that is seen upon silencing of the GFP gene. (B) C. elegans engineered to express GFP in cell nuclei. Animals on the right have been treated with a ...

In particular, a green-fluorescent protein (GFP) gene was fused with Dpp to produce a single protein product containing both Dpp and GFP domains. This fusion gene was expressed in Dpp mutant flies ...

The team has used Crispr to add a gene to rabbit embryos so they produce green fluorescent protein, or GFP. Zayner says they’re aiming to transfer the engineered embryos to female rabbits this week.

Knocking in genes allows scientists to study the effects of specific gene variants, to use reporter genes like green fluorescent protein to track gene products in time and space, to probe genome ...
